Thanks
I am submitting patch to drop count to 10,000 for 16 bit int target.
Using 32 bit counter of 1 million takes a minute or so on simulator -
which is high.
The lower count is quick and only requires a (16bit) stack limit to be
lower than 10MB - which is pretty safe.

The test appears to be unsafe. The original fault was failure to deallocate

run time error - neither of which seem certian.
It's expected to run into RLIMIT_STACK or equivalent, with an expectation
that stack limits are generally below 500MB. (A million executions of a
few instructions should be pretty fast in general.)
b) I could change n to be 32 bit on 16 bit targets (the test will then be
equally uncertain on 16 bit targets at detecting fault.)
This seems to be the natural approach.
